发明名称 Debris blower and/or vacuum devices
摘要 A debris blower and/or vacuum device is disclosed which comprises a motor unit which drives an impeller. When the device is to be used as a blower, a volute arrangement adopted for blowing in which the impeller is locatable is releasably attached to the motor unit. The blower volute includes an air inlet and an air outlet duct for expelling a stream of air created by the impeller. When the device is to be used as a vacuum, a volute arrangement adapted for vacuuming in which the impeller is locatable is releasably attached to the motor unit. The vacuum volute includes a suction duct for transporting debris to the impeller in an airstream created by the impeller and an air expelling duct for transporting debris away from the impeller in the stream of air to a collecting location.
